man cnid_metad (Administration système) - start cnid_dbd daemons on request

NAME

cnid_metad - start cnid_dbd daemons on request

SYNOPSIS

cnid_metad [-d] [ -h hostname ] [ -p port ] [ -u user ] [ -g group ] [ -s cnid_dbdpathname ]

DESCRIPTION

cnid_metad waits for requests from afpd to start up instances of the cnid_dbd daemon. It keeps track of the status of a cnid_dbd instance once started and will restart it if necessary. cnid_metad is normally started at boot time from /etc/rc or equivalent and runs until shutdown. afpd needs to be configured with the -cnidserver option in afpd.conf in order to access cnid_metad. It is possible to run more than one instance of cnid_metad on the same machine if different values for the interface and/or port are specified with the -h and -p options.

OPTIONS

-d
cnid_metad will remain in the foreground and will also leave the standard input, standard output and standard error file descriptors open. Useful for debugging.
-h hostname
Use hostname as the network interface for requests as opposed to the default localhost .
-p port
Use port as the port number for reqests. Default is 4700.
-u user
Switch to the userid of user before serving requests. This userid will be inherited by all cnid_dbd daemon processes started.
-u group
Switch to the groupid of group before serving requests. This groupid will be inherited by all cnid_dbd daemon processes started. Both user and group must be specified as strings.
-s cnid_dbd pathname
Use cnid_dbd pathname as the pathname of the executeable of the cnid_dbd daemon. The default is /usr/sbin/cnid_dbd.

CAVEATS

The number of cnid_dbd subprocecesses is currently limited to 128. This restriction will be lifted in the future.

cnid_metad does not block or catch any signals apart from SIGPIPE. It will therefore exit on most signals received. This will also cause all instances of cnid_dbd's started by that cnid_metad to exit gracefully. Since state about and IPC access to the subprocesses is only maintained in memory by cnid_metad this is desired behaviour. As soon as cnid_metad is restarted afpd processes will transparently reconnect.
